Q. The electric field of an electromagnetic wave travelling through vacuum is given by the equation$E = E_{0}\sin{(kx - \omega t)}$. The quantity that is independent of wavelength is
A) $\frac{k}{\omega}$
B) $k\omega$
C) $\omega$
D) $k$
Explanation
(a) $E = E_{0}\sin(kx - \omega t)$
Comparing with standard equation we will get
Wavelength = $\frac{k}{\omega}$
